ICVerify 4.03 (credit card processing software) does not work when Comodo is installed. That is, if you try and start ICVerify you get the hourglass for 1 second and then nothing. If you exit Comodo and then run ICVerify it still does not work.
Only way to get ICVerify working again is to uninstall Comodo. I uninstalled and reinstalled 3 times with the same results. Only when Comodo is uninstalled will ICVerify run.
I had the Comodo Basic Firewall only installed.
